Answer:
B) exposure to red light
Explanation:
Plants use a phytochrome system to sense the level, intensity, duration, and color of environmental light do as to adjust their physiology.
The phytochromes are a family of chromoproteins with a linear tetrapyrrole chromophore, similar to the chlorophyll. Phytochromes have two photo-interconvertible forms: Pr and Pfr. Pr absorbs red light (~667 nm) and is immediately converted to Pfr. Pfr absorbs far-red light (~730 nm) and is quickly converted back to Pr. Absorption of red or far-red light causes a massive change to the shape of the chromophore, altering the conformation and activity of the phytochrome protein to which it is bound. Together, the two forms represent the phytochrome system.
<span>Answer: 110.12 m/s </span>
We will use the formula A1V1 = A2V2
where 7.8 m/s is divided with 0.0085 m then multiply to 0.12 m, the result will
be 110.117 or 110.12 m/s. This is related to the continuity of fluid flow in
which as liquid moves horizontally, the same amount of liquid goes out as it comes in or the
liquid itself do not change as it moves but the speed does when the diameter changes.
Answer:
CGS means Centimeter Gram Second while FPS means Foot Pounds Second
Explanation:
FPS is the standard used to measurement of length, mass and time. The unit of length is foot.
The time is calculated as the unit of seconds. CGS is the measurement of length, mass and time in units of centimeter, gram and second respectively
Answer:
a round shape. It has its own gravity to pull itself into a round shape
Answer:
kinetic energy increases with the energy which causes the particles to move faster resulting in increases collision rates and rate of diffusion.
